I found this charger in my home and I've been using it for a few months to charge my electronics. I don't know where it came from or where it was purchased. The charger does get hot when charging a device. I do notice that it charged the devices quite fast. 
The charger in question is the counterfeit A1265 charger as I noticed from the back. It felt slightly lighter than the original genuine Apple charger I have. 
I felt suspicious of this charger due to how hot it gets when charging my devices.
